This commit adds unstable workspace support. This is extremely
bare-bones and
minimal first-pass at this.
With this change `deno.json` supports specifying `workspaces` key, that
accepts a list of subdirectories. Each workspace can have its own import
map. It's required to specify a `"name"` and `"version"` properties in the
configuration file for the workspace:
```jsonc
// deno.json
{
"workspaces": [
"a",
"b"
},
"imports": {
"express": "npm:express@5"
}
}
```
``` jsonc
// a/deno.json
{
"name": "a",
"version": "1.0.2",
"imports": {
"kleur": "npm:kleur"
}
}
```
```jsonc
// b/deno.json
{
"name": "b",
"version": "0.51.0",
"imports": {
"chalk": "npm:chalk"
}
}
```
`--unstable-workspaces` flag is required to use this feature:
```
$ deno run --unstable-workspaces mod.ts
```

This commit adds granular `--unstable-*` flags:
- "--unstable-broadcast-channel"
- "--unstable-ffi"
- "--unstable-fs"
- "--unstable-http"
- "--unstable-kv"
- "--unstable-net"
- "--unstable-worker-options"
- "--unstable-cron"
These flags are meant to replace a "catch-all" flag - "--unstable", that
gives a binary control whether unstable features are enabled or not. The
downside of this flag that allowing eg. Deno KV API also enables the FFI
API (though the latter is still gated with a permission).
These flags can also be specified in `deno.json` file under `unstable`
key.
Currently, "--unstable" flag works the same way - I will open a follow
up PR that will print a warning when using "--unstable" and suggest to use
concrete "--unstable-*" flag instead. We plan to phase out "--unstable"
completely in Deno 2.
This change adds the `--env=[FILE]` flag to the `run`, `compile`,
`eval`, `install` and `repl` subcommands. Environment variables set in
the CLI overwrite those defined in the `.env` file.
Adds a new `--lint` flag to `deno doc` that surfaces three kinds of
diagnostics:
1. Diagnostic for non-exported type referenced in an exported type.
* Why? People often forget to export types from a module in TypeScript.
To supress this diagnostic, add an `@internal` jsdoc tag to the internal
type.
1. Diagnostic for missing return type or missing property type on a
**public** type.
* Why? Otherwise `deno doc` will not display good documentation. Adding
explicit types also helps with type checking performance.
1. Diagnostic for missing jsdoc on a **public** type.
* Why? Everything should be documented. This diagnostic can be supressed
by adding a jsdoc comment description.
If the lint passes, `deno doc` generates documentation as usual.
For example, checking for deno doc diagnostics on the CI:
```shellsession
$ deno doc --lint mod.ts second_entrypoint.ts > /dev/null
```
This feature is incredibly useful for library authors.
## Why not include this in `deno lint`?
1. The command needs the documenation output in order to figure out the
diagnostics.
1. `deno lint` doesn't understand where the entrypoints are. That's
critical for the diagnostics to be useful.
1. It's much more performant to do this while generating documentation.
1. There is precedence in rustdoc (ex. `#![warn(missing_docs)]`).
## Why not `--check`?
It is confusing with `deno run --check`, since that means to run type
checking (and confusing with `deno check --docs`).
## Output Future Improvement
The output is not ideal atm, but it's fine for a first pass. We will
improve it in the future.

This commit adds `--unstable-hmr` flag, that enabled Hot Module Replacement.
This flag works like `--watch` and accepts the same arguments. If
HMR is not possible the process will be restarted instead.
Currently HMR is only supported in `deno run` subcommand.
Upon HMR a `CustomEvent("hmr")` will be dispatched that contains
information which file was changed in its `details` property.

This commit adds support for multiple entry points to `deno doc`.
Unfortunately to achieve that, I had to change the semantics of the
command to explicitly require `--filter` parameter for filtering
symbols, instead of treating second free argument as the filter argument.
`deno doc --builtin` is still supported, but cannot be mixed with
actual entrypoints.
This PR adds a new unstable "bring your own node_modules" (BYONM)
functionality currently behind a `--unstable-byonm` flag (`"unstable":
["byonm"]` in a deno.json).
This enables users to run a separate install command (ex. `npm install`,
`pnpm install`) then run `deno run main.ts` and Deno will respect the
layout of the node_modules directory as setup by the separate install
command. It also works with npm/yarn/pnpm workspaces.
For this PR, the behaviour is opted into by specifying
`--unstable-byonm`/`"unstable": ["byonm"]`, but in the future we may
make this the default behaviour as outlined in
https://github.com/denoland/deno/issues/18967#issuecomment-1761248941
This is an extremely rough initial implementation. Errors are
terrible in this and the LSP requires frequent restarts. Improvements
will be done in follow up PRs.
This commit adds "deno jupyter" subcommand which
provides a Deno kernel for Jupyter notebooks.
The implementation is mostly based on Deno's REPL and
reuses large parts of it (though there's some clean up that
needs to happen in follow up PRs). Not all functionality of
Jupyter kernel is implemented and some message type
are still not implemented (eg. "inspect_request") but
the kernel is fully working and provides all the capatibilities
that the Deno REPL has; including TypeScript transpilation
and npm packages support.
Closes https://github.com/denoland/deno/issues/13016

This allows us to opt in to extremely detailed tracing from dependency
libraries, like so:
```
cargo run --features tracing/log,tracing/max_level_trace -- test --log-level=trace -A --unstable ./cli/tests/unit/serve_test.ts
```
It will not impact normal operation as it requires the
`tracing/max_level_trace` and `tracing/log` to be active.
Note that tracing is already a dependency -- this just makes it a direct
dep of cli so we can access its features more easily.
This PR adds a test reporter for the [Test Anything
Protocol](https://testanything.org).
It makes the following implementation decisions:
- No TODO pragma, as there is no such marker in `Deno.test`
- SKIP pragma for `ignore`d tests
- Test steps are treated as TAP14 subtests
- Support for this in consumers seems spotty
- Some consumers will incorrectly interpret these markers, resulting in
unexpected output
- Considering the lack of support, and to avoid implementation
complexity,
subtests are at most one level deep (all test steps are in the same
subtest)
- To accommodate consumers that use comments to indicate test-suites
(unspecced)
- The test module path is output as a comment
- This is disabled for `--parallel` testing
- Failure diagnostics are output as JSON, which is also valid YAML
- The structure is not specified, so the format roughly follows the spec
example:
```
---
message: "Failed with error 'hostname peebles.example.com not found'"
severity: fail
found:
hostname: 'peebles.example.com'
address: ~
wanted:
hostname: 'peebles.example.com'
address: '85.193.201.85'
at:
file: test/dns-resolve.c
line: 142

```
Fix #20022, fix #19627 (duplicate)
#17333 upgraded clap from version 3.1 to version 4. clap version 3.2.0
(intentionally) broke a behavior that deno was relying on to make `deno
run --v8-flags=--help` work without specifying a file, see
clap-rs/clap#3793. The workaround was to make the script argument
required _unless_ `--v8-flags` is present. This broke the expectation
that all successfully parsed `run` commands have the script argument
set, leading to the panic on
`matches.remove_many::<String>("script_arg").unwrap()`.
Clap, as far as I was able to find out, does not currently offer a neat
solution to this problem. This PR adds logic to create and return a
custom clap error when a parsed run command does not have the script
argument.
I added an appropriate test.
This commit moves `snapshot_from_lockfile` function to [deno_npm
crate](https://github.com/denoland/deno_npm). This allows this function
to be called outside Deno CLI (in particular, Deno Deploy).
Renames the unstable `deno_modules` directory and corresponding settings
to `vendor` after feedback. Also causes the vendoring of the
`node_modules` directory which can be disabled via
`--node-modules-dir=false` or `"nodeModulesDir": false`.
This commit adds new "--deny-*" permission flags. These are complimentary to
"--allow-*" flags.
These flags can be used to restrict access to certain resources, even if they
were granted using "--allow-*" flags or the "--allow-all" ("-A") flag.
Eg. specifying "--allow-read --deny-read" will result in a permission error,
while "--allow-read --deny-read=/etc" will allow read access to all FS but the
"/etc" directory.
Runtime permissions APIs ("Deno.permissions") were adjusted as well, mainly
by adding, a new "PermissionStatus.partial" field. This field denotes that
while permission might be granted to requested resource, it's only partial (ie.
a "--deny-*" flag was specified that excludes some of the requested resources).
Eg. specifying "--allow-read=foo/ --deny-read=foo/bar" and then querying for
permissions like "Deno.permissions.query({ name: "read", path: "foo/" })"
will return "PermissionStatus { state: "granted", onchange: null, partial: true }",
denoting that some of the subpaths don't have read access.
Closes #18804.

This commit adds a "dot" reporter to "deno test" subcommand,
that can be activated using "--dot" flag.
It provides a concise output using:
- "." for passing test
- "," for ignored test
- "!" for failing test
User output is silenced and not printed to the console.
In non-TTY environments each result is printed on a separate line.
